Haim appeared on last night’s episode of The Tonight Show Starring Jimmy Fallon as they prepare to release new album I Quit on Friday. The sisters taught Fallon how to speak in their sibling unison in a cold open comedy sketch, before sitting down to discuss the record, the inspiration of 1996 movie That Thing You Do, and their childhood origins as a trio of drummers—demonstrated in a rendition of I Quit single “Relationships” that they performed on the couch with makeshift percussion found around Fallon’s desk. They eventually closed the show with “Down to Be Wrong.” Watch it all go down below.
